Embodiment

[0030] Example: Combined toxicity test of different ratios of fipronil and pyriproxyfen.

[0031] 1.1 Drugs to be tested

[0032] 96% of the original drug of fipronil and 96% of the original drug of pyriproxyfen were provided by the research and development department of Hailier Pharmaceutical Co., Ltd.

[0033] 1.2 Test target

[0034] Plutella xylostella: the third-instar larvae of sensitive Plutella xylostella were reared indoors continuously for 5 generations with the same individual size and physiological state. Temperature (25±2)°C. The relative humidity is 65%±5%, and the photoperiod is 12 / 12h (L / D).

[0035] 1.3 Experimental steps

[0036] 1.3.1 Drug preparation

[0037] Dissolve the original drug with acetone first, mix the appropriate amount of the two original drugs into several different ratios according to the results of the preliminary experiment, and then dilute each treatment with acetone into several concentration gradients for use.

Abstract

The invention relates to an insecticidal composition containing fipronil and pyriproxyfen. The effective components of fipronil and pyriproxyfen are in binary compound, the mass ratio of fipronil to pyriproxyfen is 1-50 to 50-1, the total mass of the effective components of fipronil and pyriproxyfen in the preparation accounts for 1-80% the mass of the total preparation, the rest components in the preparation are auxiliary elements acceptable in pesticides, and the insecticidal composition can be prepared into missible oil, an suspending agent, wettable powder, water dispersible granule, emulsion in water, microemulsion, granula and microcapsule formulation. The insecticidal composition is mainly used for preventing and treating pest and disease damages caused by aphids, leafhoppers, plant hoppers, bemisia tabacis, scale insects, plutella xylostellas, asparagus caterpillars, prodenia lituras, pear psyllids, thrips, imported cabbageworm and the like.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to an insecticidal composition containing fipronil and pyriproxyfen. Background technique [0002] Fipronil is a phenylpyrazole insecticide with a wide insecticidal spectrum. It mainly has gastric toxicity to pests, and also has contact killing and certain systemic effects. Its mechanism of action is to hinder insect γ-aminobutyric acid Controlled chloride metabolism, so it has high insecticidal activity against important pests such as aphids, leafhoppers, planthoppers, Lepidoptera larvae, flies and Coleoptera, and has no phytotoxicity to crops. It has a high level of control effect on diamondback moth, cabbage butterfly, rice thrips, etc., and has a long lasting effect. Chemical name of fipronil (RS)-5-amino-1-(2,6-dichloro-a,a,a-trifluoro-p-tolyl)-4-trifluoromethylsulfinylpyrazole -3-carbonitrile, whose chemical structure is . [0003] Pyriproxyfen is an insect ...
